This invention relates to heat exchangers certain refrloerating plants. In such con-.v densers thequantity of coohngwater neces. sarily usedl maybe reduced 1f the water beg.

accomplish this desirable result and inexpensive means.,

by a `simple Thep'refcrred embodiment of the inven-VA tion is illustrated in the accompanying drawings7 in which- Figure l is a vertical axial section of the 'upperpart of the condenser -shell showing the tube sheet and, the upperends of the tubes and showing mywater .detlector constructionapplied.' ,y f

Referring vfirst.-particularly to and 2, the condensershell is vshown at 11,.V the flanged tube sheet orvhead at 12, and

Y the welded joint connecting thertube sheet and shell at 13. lThe tubes are shown at 111. Y

Resting in the upper end of each tube is 'a' deflector indicated generally by the reference numeral 15. This deliector is of specialV construction and consists of a hollow cone 16 suspended with its apex upward. 4The cone and the interior surface of the corre spending tube 14. This cone is suspended and positioned by a pair of suspension lugs 17 which rest on the upper end of the tube,v

and is positioned "in ajdirection at right f angles to the lugs 17 by a pairof position.

Perforat'ions 22 allow the ;-water admitted to the top ofthe shell 2O tofall in small streams or drops ap'p'rorima telyy uniformly throughout the Varea 'of-the tube sheet 12. A pair'of lifting loops'23-vare) attached to the plate 21 andserves` as :a means for removing y,the entire distributor structure from thetop of the condenser.

Another part `Hows through the slots 26` and thence through the perforations 227 outside the register rings. Thus the rat-e offlow throughfthe central area and the surrounding annulaiarea may be Aadp'isted relatively to .each other. The Y y purpose isto secure approximately uniform iiow of water to allparts lof the tube sheet.

This water overflows lthe upper ends of theV tubes 14 and directed in part by the 'de-1 flectors 15 continues to flow in contact with the internal surface of these tubes.- Not only do the deflectors 15 direct the water ragainst the vtube walls but they arrest vand n 1 .i Y *l deflect anydrops off-'water whichmight otherwise fall directly from'arperforation beneath it.

the disturbing effect of fungus growths .v which arefencountered in this service and l-fwhi'ch make occasional cleaning necessary. Iii-this connection ka ,very simple form `of deflectorV is of the utmostimportancaas it lends itself to easy cleaning and doespnot lend itself tothe accumulation of obstructp ing growths.

lVarious changes of detail may .b'evmad'e p Y withmit'departingV from ,the spirit of the invention;

What is claimed is: t lg-The combinationwith avertical heat Vinterchanger tube of a liquidKV deflector mounted within the lupper end of the tube Vand comprising a downward and outward flaring conical deflector of'slightly smaller i diameter" thanrand mounted within the interior of the tube arranged to deflect water into Contact with; the internal wallv ofthe tube,

2.,'The combination withV a verticall 'heat '-interchanger tube of a-liquid deiiector sus peiided in the upper end of said tube, said positioning lugs adaptedA to engagetlieuppcr small streams overfthe tube area; `and a plurality of liquid' deflectors mountedv with` deflector comprising a conical member havinga base slightly smaller in diameter than the interior of the tube, and suspendingrand 'margin and the interior wall. of thev tube. e

3. The combination with a vertical shell .and tube heat interchanger of a'perforated plate Vfordistributing water uniformlyA in `in the 'upper ends ofthe various tubesA and each comprising aV conical deflector of slightly `smaller diameter than the interior ofthe tubes, arranged to defiect'the water into c`on-` taet'with the Wall of' the tube` .y Y f4. The combination with a verticalshell and tube heat interchanger, of'a .water su'pp ply arranged to discharge cooling water over the Vcenter of the upper end of the shellya horizontal perforated diaphragm interposed in the pathof such waterland adaptedl to- Ydistributesuch water inv small, streams over the tube area; and an annular Y vregiste,r-gate for controllingthe flow above the diaphragmfrom the center of the diaphragm to 'the` marginal portions thereof.

5. The combination withv a Verticalv shell and tube heat interchanger, of a water supply arranged to discharge cooling water over thecenter of the upper end of the shell; a horizontal perforated diaphragm interposed in the path of such water andadapted to distribute suoli water in small `streams over the tube'area; an annular register-'gate for Vcont-rollingothe flow above theV diaphragm e fromthecenter of the diaphragm to the marginalv portions thereof; Aand conical deflectors mounted within the Lipper ends' of the tubes and arranged to deflect the' falling water into contact with the wallsv of the tubes. Y W Y Q L '6. The combination with vertical heat interchanger tube, of an iinperforate liquid.4

deflector supportedfwithin the upper end of the tube, ,and havingV va pendant marginal rim spaced from thewall ofthe tube.

V7. The combination with a verticalfheatl interchanger tube of a downwardly and outwardly flaring liquid-deflector, of substantially conical form, recessedon its lower face to afford a pendantmar'ginal rim spaced vfrom the Wall vofthetube, said ldeflector being Inountedwithin Vsaidl tube.

. 8. Thefconibination witha vertical Lheatv interchang'er'tube, of a downwardly and outwardliyI V flaring liquidy deflector, of substantially conical fori-n, recessed on its' lower face to afford,- a pendant marginal rim spaced from the wall ofthe tube, and suspending means for` saiddefiector ada'ptedto Y restupon the upper margin of the tube.
